They tried that several years ago in the philly area. It was a flop as now there is more competition for high bandwidth.
In Philly, We have 4 choices that I know of although there may be more.
DirectTV High Speed
I currently have comcast Fios and get about 25Mbits. It costs me..... $19.95/month.
I originally signed up at 24.99, but they raised me to $42.99 after 3 months. I called up and threatened to switch Verizon for $25 and they countered with $19.95 for 18 months.
Competition is a great thing. If you have more than one provider in the area, work them against each other.
